A lifesaver for my senior dog
July 31, 2026
A couple of months ago, my 16-year old Jack Russell was on the brink of needing to be put down. The vet drew blood for a battery of tests and after that she came in the room and I asked if he was in pain from his pancreatitis and she said, 'No, he has arthritis, though'. She left and came back with a sample pack of Rejensa. I started him on it immediately and noticed a difference after about a week. It was wild because the vet called with his test results one day when he was having a particularly bad day and she said his organs are in good shape for a 16-year old. I had been thinking about making that dreaded call that very day. I decided to give the Rejensa a chance and boy, I'm glad I did. It's amazing. The Rejensa and daily hemp chews have given me back my dog again.I have my other senior dog on it, too. It's a miracle cure for arthritis.
Pros
- Works fairly fast. My dog was stumbling, falling down the stairs, falling all over the place. He can now navigate the steps and jumping on the bed. He no longer audibly groans when I move him.
Cons
- Price, of course, but I'll pay anything to help my doggos.

Noticed a change!
April 26, 2026
We have an elderly dog who is showing stiffness and slow moving. I almost immediately noticed an improvement in her jumping up and running and taking stairs like a much younger dog. It was recommended to me by someone from my vets office who had similar results with her older dog.

It's too soon to tell but my dog eats it with no problem, he won't eat anything with seafood and these don't appear to contain it so it's a win.
Pros
